Mouths

Mouths are a part of the anatomy constituting the first portion of the alimentary canal that receives food and saliva. In addition to its primary role as the beginning of the digestive system, in humans the mouth also plays a significant role in communication. While primary aspects of the voice are produced in the throat, the tongue, lips, and jaw are also needed to produce the range of sounds included in human language. Another non-digestive function of the mouth is its role in secondary social and/or sexual activity, such as kissing and other sexual purposes involving sucking and blowing.
